Abstract
The device has housing (G) with a bottom face incorporating a measuring window (7) to measure a measurement object. A displace ably mounted white reference tile located in an end region of a support plate (10) is moved into and out of the measurement optical path. The support plate recessed into the device housing in the parked position is adapted to be lifted out of the bottom face of the housing and is moved in the longitudinal direction to cover the measuring window with the end region incorporating the white reference tile in the operating position.
